Nice work rymnd! I like the direction you have taken.
I'm going to pursue a similar construction, using 6 dowel pins and 3 ball bearings to provide a kinematic coupling. In your construction, you rely on a second set of magnets to provide the closing or clamping force. You have great control over your clamping force because you can accommodate magnets of different size. A downside is that you have added components and space claimed because you have hardware for alignment and hardware for clamping force.
I plan on integrating alignment and clamping force by using the same concept as implemented with this rack, consisting of magnets sandwiched between two ferrous plates:

(mcmaster: Screw-Mount Magnetic Tool Holder Rack)
In this case, two small disc magnets sandwiched between two locating dowel pins, oriented exactly as you have. I am waiting on hardware to show up in the mail to start playing with the magnets and to see how much clamping force is generated.
How are you holding your unused tool holders? Have you had to adjust clamping force?
Cheers!
